BINDER.

Appcatlon led April 7, 1924. Serial No. 704,655.

This invention relates to improvements in binders.

My improved binder is designed for the binding of sheets ermanently and is particularly designed y me for the permanent bindin of sheets which have been used in loose s eet accounting, but which it is desired to reserve for ermanent record. My improve binder is, owever, desirable for l0 use in the binding of any sheets, catalogs or the like.

The main object of this invention is toy provide an improved binder which is simple and economical in its parts and one which l5 may be quickly assembled to permanently bind and secure the sheets.

A further object is to provide an improved binder having these advantages lfrom which it is quite impossible to release the sheets without destroying the binder or the sheets.

Objects pertaining to details and economies of construction and operation of my improvements will definitel appear from the detailed description to ollow.

I accomplish the objects of my invention by the devices and means described in the following specification. rlhe invention is clearly defined and ointed out in the claim.

A structure embo ying the features of my invention is .clearly illustrated in the accompanying drawin forming a part of this application, inw ich:

Fig. I is a perspective view of a binder embodying the features of my invention.

Fig. II is a detail vertical section on a line corresponding to line 2 2 of I.

Fig. III is a detail horizontal section on a line corresponding to line 3-3 of Fig. II.

In the drawing the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of reference indicate similar parts in all of the views.

Referring` to the drawing, the sheets 1 have perforations 2 thereinto receive binding posts. My improved binder comprises a pair of binder bars 3 and 4 secured to the covers 5 by the hinges 6. v These binder bars are secured in clamping relation to the sheet by means of the binding posts comprising a relatively fixed member designated generally by the numeral 7 which is'made up of sect1ons 8, 9 and 10, the bottom section 8 being riveted to the bottom binder bar. The section 10 is a terminal section while one or more of the sections 9 vare used, as may be desired.

The terminal section 10 has a plurality of annular grooves 11 formed therein forming annular ratchet teeth 12. The'coacting post member 13 is arranged through the hole 14 in the binder bar 3 and has a heady 15 engaging the outer side of the binder bar. This post section is tubularv and longitudinally slitted at 16 providing a plurality of spring pawls 17, the inner ends of the pawls being turned inwardly at 18 to engage the ratchet teeth of the terminal memberl 10.

With the parts thus formed the post 7 is built up to the desired length, that is, to accommodate the particular body of sheets which it is desired to bind, the sheets are arranged thereon, the binder bar 3 superimposed and the post member 13 introduced thereto and forced downwardly as far as possible, clamping the top binding member upon the sheets and permanently securing the parts together, as it is impossible to disengae the ratchet teeth, the same being engage and held by the sheet body so that they cannot be sprung outward without such mutilation of the sheet body or the binders as to practically destroy the same. My improved binder is very economical in its parts, may be quickly adjusted to the sheet body, and securely and permanently binds the same.

Having thus described my invention what I claim as new and desire to secure by Letbinder bar to telescopingly embrace said terminal section, said tubular member being longitudinally slitted providing a plurality of spring pawls having inturned ends coact- 5 ing with the said teeth when the parts are telescoped Within the said body, the perforations n said sheet body being of such diameter as to closely embrace said tubular member preventing disengagement of said spring pawls.

In Witness whereof I have hereunto set my hand.

GEORGE P. WIGGINTON.
